I'm trying to set up Postfix to use two smarthosts. All mail sent from domains example.(com|org) should be sent over smtp.gmail.com (default smarthost) and mails from Domain.A should be sent over mailgw.Domain.A (MUA is MS Exchange). I set everything up like in the configuration below. However delivering the mail fails with 535 Authentication unsuccessful. I have tried to log in via AUTH LOGIN and telnet/openssl. This worked. So I have no idea, why authnetication doesn't work here. Do you have any hints what I'm doing wrong?

just disable NTLM auth on your SMTP client been there, done that on Fedora "yum remove cyrus-sasl-ntlm" and restart postfix should also be possible with a config change, Google!
